In 2008 and 2009, the Institute of Archaeology UW team, conducted by the author, undertook excavations on newly discovered Early Medieval burial-site in Aleksandrowo, the Podlaskie Voivodeship. During two seasons there were discovered 8 flat graves with stone-settings - a typical form of graves in this region, between the second half of eleventh and thirteenth century. They consist of large stone surroundings and a few-layered cobblestones, covering the remains of the dead. Originally all of them held inhumation burials, which were not preserved because of shallow placing of the skeletons. Apart from sherds, in the graves, there were found some metal items from the dead’s equipage, like temple rings, finger rings, knives, arrow heads, ringed pin, flint, and others. The explored part of the site is dated back approximately to the second half of the 11th and the 12th c.
